陈少杰 eb2ab0afcf Preserve diagnostics in live-mode failure payloads ... The previous hardening pass still dropped source diagnostics and data-quality context once live-mode serialized a dual-lane failure. Keep those fields when a structured CombinedSignalFailure reaches the websocket layer so consumers can distinguish provider mismatch, stale data, and other degraded cases even when no final signal exists. Constraint: Follow-on fix after 63858bf should stay minimal and not reopen unrelated executor/calendar work Rejected: Fold this into a larger amend of the prior commit | history is already shared and the delta is a single behavioral correction Confidence: high Scope-risk: narrow Reversibility: clean Directive: When failure exceptions carry structured diagnostics, live serializers must preserve them instead of flattening to a generic message Tested: python -m pytest web_dashboard/backend/tests/test_executors.py web_dashboard/backend/tests/test_services_migration.py web_dashboard/backend/tests/test_api_smoke.py orchestrator/tests/test_market_calendar.py orchestrator/tests/test_live_mode.py orchestrator/tests/test_application_service.py orchestrator/tests/test_quant_runner.py orchestrator/tests/test_llm_runner.py -q Tested: python -m compileall orchestrator web_dashboard/backend Tested: npm run build (web_dashboard/frontend) Not-tested: real websocket consumers against provider-backed failure paths		2026-04-14 02:10:31 +08:00
